Complex Event Processing and FX market aggregation
Today we announced the Progress Apama FX Market Aggregation Accelerator. There is a lot of talk about algorithmic trading, but little hard discussion about the specific differences among asset classes and the styles of trading in each. We've spoken about the differences between FX, equities, fixed income, and derivatives, etc. The approach we take with our customers is to learn from experience while we work with them with specific use cases, and then generalize common best practices that can be used to address similar customer demands.
An example of this is the increased usage of algorithmic trading in FX, we have released a specific set of layered functionality foreign exchange (FX) algorithmic trading. This package includes adapters withpre-built Apama trading dashboards and foundation on top of Apama for FX algorithms. Theoffering helps both sell- and buy-side traders develop and deployhigh-frequency foreign exchange trading strategies that capitalise onproprietary trading techniques, integrating with major FX aggregators,Electronic Crossing Networks (ECNs) and direct bank connections.
More information on the news can be found here.

       Header	  Description
       -------------------------------
       Sif	     Source Interface ifIndex.
       DiF	     Destination Interface ifIndex.
       Pr	     Protocol.
       P	     Protocol.
       SrcP	     Source Port.
       DstP	     Destination Port.
       Pkts	     Packets.
       Octets	     Octets (Bytes).
       Active	     Time in ms the flow was active.
       B/Pk	     Bytes per Packet.
       Ts	     Type of Service.
       Fl	     Flags, for TCP the cumulative or of the TCP control bits.
       srcAS	     Source AS.
       dstAS	     Destination AS.
       Start	     Start time of the flow.
       End	     End time of the flow.
       router_sc     V7 IP address of router producing shorcuts.
       peer_nexthop  V6 IP address of peer next hop IP address.
       encap i/o     Version 6 only.  Encapsulation size in/out
       duration      Time in ms the flow was active.
       input	     Input Interface ifIndex.
       output	     Output Interface ifIndex.
       flows	     Number of aggregated flows.
       mTos	     V8.x ToS of pkts that exceeded the contract.
       xpackets      V8.x Packets that exceed the contract.

	   2 2 line candidate TCP syn attack flows
	   3 1 line, no interfaces, decimal ports
	   4 1 line with AS number
	   5 1 line, 132 column
	   6 show ip accounting emulation
	   7 1 line, 132 column +router_id
	   8 1 line, 132 column +encapsulation
	   9 1 line with tag values
	  10 AS aggregation
	  11 Protocol Port aggregation
	  12 Source Prefix aggregation
	  13 Destination Prefix aggregation
	  14 Prefix aggregation
	  15 Destination aggregation (Catalyst)
	  16 Source Destination aggregation (Catalyst)
	  17 Full Flow (Catalyst)
	  18 ToS AS Aggregation
	  19 ToS Proto Port aggregation
	  20 ToS Source Prefix aggregation
	  21 ToS Destination Prefix aggregation
	  22 ToS Prefix Aggregation
	  23 ToS Prefix Port aggregation
	  24 Full (Catalyst)

       -h	 Display help.

       -l	 Unbuffer output.

       -n	 Use symbolic names where appropriate.

       -p	 Display header information.

       -w	 Wide output.
